2.DEFNOTESNone.
Note:
Supply no.2 is for the following components:
– pedal sensor (gang 2),
– EGR valve position sensor,
– cruise control/speed limiter button (on steering wheel),
– refrigerant pressure sensor.
Measure the feed voltage on the following sensors:
– Connection code 3LU of component 921.
– Connection code 3AAQ of component 1290.
– Connection code 3GC of component 1460.
– Connection code 38Y of component 1202.
If the voltage is less than 4.9 V, disconnect the sensor connectors one by one.
If, after disconnecting the pedal sensor, the voltage is still too low,
Check the insulation to earth of the following connection:
– Connection code 3LU between components 120 and 921.
If, after disconnecting the EGR valve, the voltage returns to normal,
Check the insulation to earth of the following connection:
– Connection code 3GC between components 120 and 1460.
If, after disconnecting the differential pressure sensor, the voltage returns to normal,
Check the insulation to earth of the following connection:
– Connection code 3AAQ between components 120 and 1290.
If the voltage returns to normal after the coolant pressure sensor is disconnected,
Check the insulation against + 12 V of the following connection:
– Connection code 38Y between components 120 and 1202.
If the fault is still present, check the conformity of ET413 Cruise control/speed limiter function
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Clear the faults created by the multiple disconnections.
Carefully examine the engine management computer connections (for conductive particles, bent pins).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

connections:
– Connection code 3ABS,
– Connection code 3ABT,
between components1589 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical

Check for the earth on the connector of the turbine upstream temperature sensor:
– Connection code 3ABT of component 1589.
Apply TEST 4 Turbocharged air inlet circuit check.
If the fault is still present, warm up the engine until parameter PR064 coolant temperature = 80°C.
Then run the engine at fast idle speed: PR055 engine speed = 1500 rpm for 2 minutes.
If PR667 Turbine upstream temperature remains fixed at 200°C, replace the turbine upstream temperature
